A Deep Dive into the Rising Threat of Advanced Phishing Kits Exploiting Trusted Platforms
Cybersecurity is once again being tested as attackers evolve beyond the standard phishing playbook. In a new wave of attacks uncovered by Darktrace’s Security Operations Center (SOC), cybercriminals are deploying advanced Adversary-in-the-Middle (AiTM) techniques to bypass even the most robust security measureâmulti-factor authentication (MFA). What’s striking about this latest campaign is the use of legitimate platforms like Milanote and the deployment of phishing kits such as Tycoon 2FA and Mamba 2FA to harvest credentials and session tokens in real-time.
Unlike traditional phishing, this new breed of attacks doesnât just stop at stealing passwordsâit allows hackers to hijack live sessions, gain persistent access to SaaS accounts, and invisibly embed themselves within corporate communication streams. The stakes are high, especially when attackers gain control over sensitive business functions such as invoicing and email correspondence. Here’s a detailed breakdown of how the attack works, whoâs being targeted, and what cybersecurity teams can do to defend against this next-gen threat.
Highlights of the Attack Campaign (Approx. )
- Attack Type Identified: Darktrace analysts flagged an AiTM phishing campaign targeting SaaS accounts.
- Tools Used: Attackers employed advanced phishing kits such as Tycoon 2FA and Mamba 2FA.
- MFA Bypassed: The campaign demonstrates successful circumvention of multi-factor authentication systems.
- Initial Entry Point: The legitimate project management platform Milanote was exploited as the phishing vector.
- Weaponization: Milanoteâs email infrastructure was manipulated to mimic credible corporate emails.
- Social Engineering: Emails included references to internal users, credible links, and deceptive payloads.
- Redirection Strategy: Victims were funneled through Cloudflare Turnstile challenges to mask malicious intent.
- Credential Theft: Fake login pages harvested passwords, session cookies, and MFA tokens in real-time.
- Session Replay: Attackers used stolen tokens to replay sessions and bypass security.
- Case Study: One enterprise saw 19 users targetedâone account was compromised after clicking the payload.
- Geolocation Red Flag: Logins detected simultaneously from Germany and the U.S. triggered alerts.
- Persistence Tactics: Hackers created email rules to hide Milanote references and retain inbox access.
- Malicious Outcome: Attackers altered invoicing emails, a precursor to Business Email Compromise (BEC).
- Anonymity Tools: Proxy and VPN services masked attackersâ origins.
- Global Reach: The campaign is part of a wider international effort, with phishing kits in multiple languages.
- Obfuscation Features: Phishing sites blocked right-clicks and copying to hinder analysis.
- As-a-Service Model: Tycoon 2FA is distributed via Phishing-as-a-Service (PhaaS) models since mid-2023.
- SOC Response: Darktrace teams neutralized threats through account lockdowns and session terminations.
- Recovery Efforts: Organizations reset credentials and secured compromised environments.
– Ongoing Threat: Even modern defenses like MFA
- User Training Not Enough: Despite awareness efforts, users still fell for deceptive messages.
- Security Gaps: Trusted platforms like Milanote are now threat vectors.
- Security Recommendations: Anomaly-based detection and automation are crucial.
- Key Takeaway: Sophisticated phishing bypasses traditional tools; new layers of defense are essential.
- Corporate Impact: Invoicing fraud and data exposure are key risks.
- Adversarial Evolution: Attacks are no longer simple but technically layered and persistent.
- Monitoring Required: Continuous behavioral analysis is the next frontier in threat detection.
- SOC’s Role: Centralized, proactive monitoring enabled swift resolution.
- Zero-Day Risk: Attack techniques evolve faster than most detection systems can adapt.

Deep Analysis of the Growing Threat from AiTM and PhaaS-Enabled Phishing Campaigns
The Darktrace discovery underscores a pivotal moment in cybersecurityâa phase where attackers are no longer just stealing passwords but hijacking authenticated sessions in real time. The use of AiTM kits like Tycoon 2FA marks a shift in attacker sophistication and intention. These tools allow threat actors to exploit trust, not just technology.
The abuse of
Moreover, the campaign reveals that MFA is no longer a fail-safe. Session hijacking using real-time interception tools renders MFA tokens obsolete once they’re stolen. This has profound implicationsâorganizations that rely solely on MFA as their ultimate barrier must now reassess their security architecture.
The role of anomaly-based threat detection emerges as crucial. Unlike rule-based systems, behavioral analytics can identify when something doesnât “feel right”âlike simultaneous logins from geographically distant locations or unusual inbox activity. In the example cited, security alerts were triggered by a login discrepancy, but unfortunately, the attackers had already gained access by that point.
Email rules created by the attackers to delete or hide security warnings showcase the persistence of modern threats. This isn’t a hit-and-run phishing incident; itâs a well-planned invasion aiming for long-term control.
The SaaS environment is particularly vulnerable. Many of these applications are accessible from anywhere in the world, rely heavily on email communications, and support automation. Once an attacker gains access, the damage potential multipliesâranging from data theft to invoice manipulation and eventual financial fraud.
One particularly concerning element is the delivery model of these phishing kits. Phishing-as-a-Service (PhaaS) democratizes access to high-end attack tools, enabling even low-skill cybercriminals to conduct sophisticated campaigns. With polished interfaces and multi-language support, these kits are designed for mass exploitation.
The use of VPNs and proxies also complicates traceback efforts. Attack attribution becomes nearly impossible, giving attackers more confidence to scale their operations.
In response, SOC teams must evolve from reactive to proactive. Automation in detection, response, and recovery is no longer optionalâit’s a necessity. Artificial Intelligence, machine learning, and behavioral analytics should be core elements of modern security operations.
Training also plays a critical role but must be paired with technical safeguards. A well-trained user may still be deceived by a convincingly legitimate emailâespecially when it mimics a platform they know and use.
Finally, organizations must develop incident response playbooks specifically tailored to AiTM attacks. These must include steps for real-time token invalidation, cross-platform session purging, and forensic email rule audits.
This is not just an alertâitâs a wake-up call. Cybersecurity strategies must adapt or risk becoming irrelevant in the face of ever-evolving adversaries.
Fact Checker Results:
- MFA alone is no longer sufficient protection against AiTM phishing kits.
- Legitimate platforms like Milanote can be exploited as phishing vectors.
- Phishing-as-a-Service kits like Tycoon 2FA are widely distributed and actively used.
Prediction:
Expect a significant rise in AiTM-based phishing attacks over the next 12 months, especially targeting SaaS platforms through reputable services like Slack, Trello, or Dropbox. As PhaaS models grow in popularity, low-level hackers will gain access to high-level tools, increasing the scale and success rate of such campaigns. Only a fusion of human vigilance, AI-driven detection, and automated response will be enough to counteract the coming wave.
